NTSB Issues Safety Recommendation A-17-011 to FAA and EASA for Airbus Helicopters AS350-Series Dual Hydraulic Systems

The National Transportation Safety Board (NTSB) has issued Safety Recommendation A-17-011, designated under reference number CEN15MA290. This recommendation is addressed jointly to the Federal Aviation Administration and the European Aviation Safety Agency. The directive requires that once the actions requested in Safety Recommendation A-17-10 are completed, operators of Airbus Helicopters dual-hydraulic AS350-series helicopters must incorporate specific changes to their dual hydraulic systems. These mandated modifications aim to ensure adequate pedal control hydraulic assistance and mitigate the possibility of pilot error during any check of the hydraulic system. The NSB emphasizes the necessity of these structural and procedural updates to enhance operational safety standards for this specific helicopter series.
